An imaging device ( 10 ) for a printing form ( 12 ), has at least one first and one second laser diode bar ( 14, 16 ), the laser diodes ( 18 ) on the laser diode bars ( 14, 16 ) being disposed in lines. The device includes a first and a second micro-optics ( 21, 22 ) for generating aberration-corrected intermediate image spots of the laser diodes ( 18 ) and a macro-optical imaging optics ( 23 ) for generating image spots ( 24 ) on the printing form ( 12 ). The first and the second micro-optics ( 21, 22 ) are positioned in such a way in the emission regions of the first and second laser diode bar ( 14, 16 ) that the image spots ( 24 ) of the laser diodes ( 18 ) of the first and second laser diode bar ( 14, 16 ) lie at disjoint positions on the printing form ( 12 ), substantially along a spanning polyline ( 30 ). Also, a method is provided for arranging optical components in an imaging device ( 10 ) for a printing form ( 12 ).
